Abstract

Rice (Oryza sativa.L) is an important crop in many regions. Kuantan Singingi has local rice that can be developed. The aim of the research is to obtain mutants with early age characteristics and short stem posture through gamma ray induced mutations.Study This has held start from November 2023-April 2024. Place research in rice fields cistern Rain village Pebaun Upstream . Subdistrict Kuantan Homecoming Regency Kuantan Singingi. The design used was a non-factorial Randomized Block Design (RAK). The factors are the irradiation dose administered (R0) without radiation as a control and radiation with 300 Gy (effective dose in previous research). Each treatment was repeated 5 times, using 600 plants per treatment. The research results showed that rice plants that were irradiated with 300 Gy had shorter flag leaf lengths compared to those without radiation. Flowering time at 300 Gy results in a shorter flowering time compared to without radiation. The harvest time for rice irradiated with 300 Gy results in a longer harvest period compared to without radiation. Meanwhile, for the length of rice panicles irradiated at 300 Gy, the panicle length was longer than without radiation. There is still a need for desirable mutant characters to be used as further breeding material
